#1272: Unable to run mpp.py

 Priority:  high                |   Milestone:  Untriaged

--------------------------------+-------------------------------------------
 There is a problem executing mpp.py.

 There is a error code mentioned in the masquerade.sh (shown below) and it
 appears inspite of commenting the lines(the same code asks to comment the
 lines to prevent displaying the error).As a result of this we are unable
 to run the MP successfully.
